Hi

While working with wine, I found the way how wine handles the
environment.

example for "TMP":
1. HCU\Environment\TMP
2. HKLM\System\CurrentControlSet\Control\Session Manager\Environment\TMP
3. $WINETMP
4. $WINEPREFIX/config (TEMP)
5. Buildin Default (c:\windows\temp)

During "wineprefixcreate", "TMP" and "TEMP" are created for entry 2
(HKLM..) from entry 4 ($WINEPREFIX/config : TEMP) with a fallback to
entry 5 (c:\windows\temp), but entry 3 ($WINETMP) is ignored.

When I delete the entry 2 (HKLM..), then entry 3 is used ($WINETMP).

IMHO, "$WINETMP" should overwrite all other locations.

PS: Tested only "WINETMP", but there are also $WINETEMP, WINEHOME and
WINEPATH.
